So, I've spent the last several days finishing the project. Sorry, don't have any video of how it sounds yet, but it has surpassed my expectations by firing it out the back door into the yard. Not much more than firing pin noise and the bullet hitting the dirt.
The project started with an old Lakefield (pre-savage arms) Mk2 bolt action. This being its' 50th birthday this year, I wanted to use it as the host because it's been a really good gun even after all these years.
Anyway, wanted to share some pics.
While I was waiting on things to be approved, I worked on things that I didn't need a stamp for so it wouldn't take as long to finish the project.
Barrel was shortened and threaded and recrowned.
In order to accommodate the larger diameter suppressor tube, I hand sanded the barrel channel on the stock so it would fit. This took a lot more work than I had expected even while using 80 and 120 grit paper. I just used a scrap piece of tube the diameter that I was going to use with the sandpaper wrapped around it so once it was finished, the barrel and suppressor sleeve would be freefloated from the stock.
Since one of the main gripes about the Savage stocks is that they are a little on the flimsy side, I decided to bed the stock and use a long aluminum rod insert epoxied in place to strengthen it and make it much more rigid, which it did.
I had to dremel through the ribs to accommodate the Al rod.
I did a water immersion camo dip on all the pieces. Receiver, scope and rings, stock. Basically the entire exterior got a camo job since I plan for it to be my squirrel gun. But I mainly did it just so everything would blend in together and so it wouldn't really scream "SUPPRESSED GUN" at first glance.
I also modified a scrap piece of picatinny rail and drilled and tapped it to make a scope rail. I milled the area away over the ejection port similar to how EGW makes theirs.
I also liked the "tactical (I hate using that term) bolt handle on the FVSR, so I made a new handle and epoxied it in place. I also changed the angle of the handle somewhat to make it easier to cycle the bolt with just moving my trigger finger and thumb. Here's the old bolt handle. You'll see the new one in the photos below of the whole gun once it was together.
Alright, now with that part of the project out of the way, now to concentrate on more of what we're here for.
The shhhh.
Rear cap is made long and hollowed out in front in case I ever port the barrel to act as a deflector so jetted gas and lead doesn't score the inner suppressor tube.
A few thick O rings to help seal the tube once it's in place
The monocore is pinned and tigged to eliminate the need to double stamp the gun.
Here it is once I filed the excess down.
The suppressor tube has no threading on it. It tensions back in place over the rear endcap when you tighten the front cap down into the monocore. I made the front of the monocore a female thread (1/2-28 to make my life easy) and essentially made the front endcap like a hollow bolt with a bore through it of course. The main reason why I did that was I didn't want to use up too much space on my monocore doing a male thread on the end of the stack. By going with a female thread, allowed me to use all the space that I had to work with and gave me one more baffle than I would've had the other way. Not shown is the .002" shim stock that will wrap around the monocore to keep the suppressor tube from seizing up. It will wrap around the core and fit between the two O rings.
I was afraid it would be far too cold to do the water immersion graphic dip and clearcoat on the suppressor body and endcaps, but it warmed up just enough to get it done late this evening.
